Quick comparison

These apps focus on different things. Some estimate personal burn risk, while others offer forecasts, peak-UV alerts, shade maps, or exposure tracking. Prices are listed as unknown because they weren’t confirmed in the supplied app details. WHO says SunSmart is available on both major platforms, but its exact store-page URL could not be confirmed.

1. UVLens - UV Index

Best for: Personalized burn-risk guidance on iPhone.

UVLens - UV Index combines daily UV forecasts with a skin-type quiz to estimate when you might burn. The estimate puts a general UV reading in context when you’re deciding how long to stay outside.

Sunscreen reminders add a useful prompt to the forecast. The app’s main draw is its skin-type-based burn-risk estimate, rather than the UV level alone.

2. SunSmart Global UV App

Best for: Straightforward sun-protection timing.

SunSmart Global UV App shows the UV level for a location and highlights times when sun protection is needed. It’s a simple option if you want a reading paired with a clear timing cue, rather than a set of tracking tools.

The World Health Organization says the app is available on the Apple App Store and Google Play. Its main feature is time-slot guidance that connects UV readings with when to protect yourself.

3. UV Index: Forecast & Shade Map

Best for: Finding lower-UV times and shaded areas.

UV Index: Forecast & Shade Map shows current and forecast UV levels, including lower-UV hours that can help you choose when to go outside. Its interactive shade map can also help you find a less exposed spot.

The app includes sunscreen reminders and widgets. The shade map sets it apart from apps that stick to forecasts and UV readings.

4. UVmeter - UV Index & Forecast

Best for: Hourly readings and peak-UV alerts.

UVmeter - UV Index & Forecast pairs real-time UV readings with hourly forecasts, so you can follow conditions through the day instead of checking just once in the morning. It also offers protection recommendations to help make sense of the readings.

Widgets and listed Apple Health integration are also included. One useful feature is its peak-UV alerts, which let you know when conditions reach their daily high.

5. Sunbeam: UV Index Tracker

Best for: Tracking daylight exposure alongside UV forecasts.

Sunbeam: UV Index Tracker provides hourly UV forecasts and alerts, helping you keep track of conditions throughout the day. It also offers exposure insights and tools for tracking daylight time and vitamin D.

Widgets are included, too. Sunbeam stands out for its daylight and vitamin D tracking, making it a broader exposure tracker than an app focused only on current UV levels.

6. UVIMate - UV Index Now

Best for: Android users who want current UV information and simple guidance.

UVIMate - UV Index Now is an Android option. Its Google Play listing describes a real-time UV index forecast and sun-safety guidance, giving you a quick way to check conditions and get basic help interpreting them.

A widget lets you check UV information from your home screen. That’s handy if you want a quick reading without opening the app each time.

7. UVLens

Best for: Android users who want burn-time estimates and reminders.

UVLens is available on Android, according to its official site. The site describes hourly UV forecasts and personal burn-time estimates, so you can check changing conditions and see an estimate based on your burn time.

The app also includes sunscreen reminders. Its personal burn-time estimate gives you an individualized reference alongside the forecast.

How we picked these apps

We focused on apps with UV readings or forecasts and a clear sun-safety use. We compared practical features such as peak-UV alerts, protection guidance, shade maps, reminders, and exposure tracking.

Platform availability comes from the supplied official app listings or descriptions on official sites. Different features will suit different needs. A shade map may help when planning a walk, while someone else may prefer a burn-time estimate or a reminder.

Frequently asked questions

What should I look for in a UV index app?

Location-specific readings show conditions where you’ll actually be, and forecast timing can help you plan outdoor activities around higher or lower UV periods. Think about whether alerts, protection guidance, shade maps, or reminders would be useful to you. Check that the app works with your phone before choosing.

How do I use a UV index app to plan sun protection?

Check the UV level and forecast before heading outside, then check again as conditions change. Protection prompts can help you decide when to seek shade or cover up. An app is a planning aid, though, not a substitute for personal judgment about your situation.

Are UV index apps available for both iPhone and Android?

Yes. This roundup includes apps for iOS and Android. The iOS-specific options are UVLens - UV Index, UV Index: Forecast & Shade Map, UVmeter, and Sunbeam. UVIMate and UVLens are Android options. WHO describes SunSmart as available on both platforms, though its exact store-page URL wasn’t confirmed here.

The verdict

The best fit depends on what you need and which phone you use. On iPhone, UVLens - UV Index pairs daily forecasts with a skin-type-based burn-risk estimate and sunscreen reminders.
